Things I liked:unit has nice fit & finish, easy to install & adjust. nice low profile on my silver streak c9a.Things I would have changed:addition of secondary hash mark on the windage adjustment, similar to the elevation adjustment - to show incremental changes.What others should know:need to remove rear sight.

Things I liked:when i opened the box & held this in my hand, i knew where my $400+ went. nice weight to it, all metal construction - no skimping here. very nice fit & finish.Things I would have changed:expensive but no complaintsWhat others should know:my 10clip co2 357 is fun to shoot but it's anemic power is a minus. my single shot multi-pump 1377 has the power but pumping 10x gets old fast. this springer pistol is my go-to gun - cock it, load it, shoot it. accurate at 10m, weaver stance, full cock w/ crosman silver eagles.

Things I liked:lead free, light weight. accurate in certain low power guns.Things I would have changed:improve the quality control - 20% of the pellets are mis-shapened. they do not fit in the breech or too loose or too tight. why so costly? though it's actually less expensive to purchase them here at PYRAMYD (buy 3, 4th is free) than the local shops in town.What others should know:breech loading problems in my 1377 so i will NEVER use them for this gun. i always have to jam these in, many other pellet brands just fit right in. they work GREAT for my 435fps crosman 357 co2. beeman p1 LOVES them.

Things I liked:overall agreement with positive attributes that have already been said.Things I would have changed:heavy trigger pull, still trying to get a feel for when it breaks.What others should know:before purchasing, must read blog report by B.B. Pelletier on this particular airgun. many good suggestions & tips. i wished i would have read it before i made my purchase. was unable to fill the rifle with air, did not have the proper connections from handpump to rifle - had to order the Pyramyd Air Quick-Disconnect male fitting and switch out the fill port on the rifle. iron sight shot very low of the target even at max adjustment. i will file down the front sight to get a more agreeable result.

Finally got a chrony to see what my rifle can do. Whelp, here are my results: AccurateMold 50-165A 176grain 200bar hand pump gauge = 610.87 fps@146 fpe 1. 610.9 2. 627.8 3. 627.2 4. 636.5 5. 627.6 6. Err 7. 624.4 8. 521.7 Next test will be how accurate at 50 yds with this same projectile. Did not want to alter gun so no filing of sites, I just put a scope on it.

Things I liked:crisp trigger, accurate, impressive quality, overall fit & finish.Things I would have changed:pricey but you get what you pay for. be careful as it may pinch when cocking (ouch!)What others should know:i wanted this single pump for 10M target shooting. fits this intended purpose flawlessly.

Things I liked:works well on my Sam Yang .50cal dragon clawWhat others should know:had to drill a smal hole into the rifle 11mm dovetail rail to accept the stop pin from this adapte. works well, i have no worries about scope creep.

Things I liked:perfect fit for sam yang dual tank .50cal dragon clawThings I would have changed:perfect, needs no changeWhat others should know:removed the original sam yang probe & replaced it with this qd fitting, makes filling with tank easier

Things I liked:fits great on the 1377 pistol turning it into a carbineThings I would have changed: perhaps an updated design so a proper eye level cheek weld can be achievedWhat others should know:for my 1377 pistol to carbine conversion, i needed to add an sks cheek piece to raise my eye for a better cheek weld
